The Venn diagram below shows the dinner orders for a local restaurant.
This was submitted before, but no one answered. Thanks!

How many people did NOT order steak for dinner?

Steak, chicken & fish were order. In the Venn circles, the total that did not order steak was 56. There is the number 43 in the left lower corner inside the rectangle that the circles are in. Is this included in the total?

It sounds like your universe includes 43 people that did not order any of the meal choices. Ignore them in all calculations, unless you are asked a question like "what % of the diners ate chicken?" Then you'd have to figure out how many ate chicken and include everyone. That would be the sum of all the people in the circles plus the outsiders (43).
